The Terms of Sale for the Google Glass Explorer edition has been found to forbid the reselling or loaning of the device, reports Wired. The much-hyped Google smart eyewear has been in hot demand since Google made the device available for purchase by developers following a competition to get early access to a limited number of the devices. While few are quibling over Google taking taking steps to avoid scalpers selling on their device for a profit, the inability for users to loan their Google Glass device has been criticized as being overly restrictive.

"You may not resell, loan, transfer, or give your device to any other person," reads Google's Terms of Sale. "If you resell, loan, transfer, or give your device to any other person without Google's authorization, Google reserves the right to deactivate the device, and neither you nor the unauthorized person using the device will be entitled to any refund, product support, or product warranty."

Google hasn't offered public comment on the matter, and is also yet to indicate whether it will apply the same terms to sales of the Google Glass when the device goes mainstream as expected before the end of the year. As CNET
has also highlighted, Google Glass Explorer edition owners are also not permitted to "serve or include any advertisements" on the devices, and they "may not charge" users to download apps to the device either.
